The utility model discloses a combined type transparent substrate with a heat insulation layer and a combined type transparent substrate system. The combined type transparent substrate with the heat insulation layer comprises a first transparent substrate and a second transparent substrate which are arranged in a stacked mode. The first transparent substrate is provided with a first inner surface facing the second transparent substrate and a first outer surface deviating from the second transparent substrate, and the second transparent substrate is provided with a second inner surface facing the first transparent substrate and a second outer surface deviating from the first transparent substrate; the combined type transparent substrate of the heat insulation layer further comprises a light blocking layer, a light adjusting layer and a heat blocking layer which are arranged together at the same time. One or more of the light blocking layer, the light adjusting layer and the heat blocking layer are arranged on one or more of the first inner surface, the first outer surface, the second inner surface and the second outer surface, and the heat insulation effect can be remarkably improved.

The invention belongs to the technical field of functional composite materials, and particularly relates to a hollow porous magnetic carbon fiber framework material, a composite coating with electromagnetic wave absorption and anti-corrosion functions, a preparation method and application. The hollow porous magnetic carbon fiber framework material is prepared by adopting a method comprising the following steps: transferring a mixture of nickel nitrate hexahydrate, 2, 5-dihydroxyterephthalic acid and DMF (Dimethyl Formamide) into a reaction kettle, and heating for reaction to obtain a nickel metal organic framework material; taking a mixture of PAN, copper nitrate monohydrate, a nickel metal organic framework material and PMMA as a shell layer solution, taking a polymethyl methacrylate solution as a core layer solution, and performing coaxial electrostatic spinning to obtain a core-shell structure nanofiber felt; and carrying out pre-oxidation, template sacrifice and carbonization treatment. Impedance matching of the coating filler can be effectively optimized, and excellent electromagnetic wave absorption performance is achieved through the synergistic effect of dielectric loss, magnetic loss and multi-interface polarization.

The application discloses an organic annulus protection fluid for oil and gas wells and a preparation method thereof. The annulus protection fluid comprises 0.01-3wt% of active polymer, 0.1-5wt% of oxygen scavenger, 0.1-2.5wt% of bactericide, 0.1-0.5% of pH regulator, and the rest is water. The active polymer in the annulus protection fluid is copolymerized from N-acryloyl morpholine and acrylate compounds. The annulus protection fluid has good chemical stability, can effectively delay the corrosion rate of the casing and the oil and gas pipeline, solve the problems of fouling, bacterial reproduction, under-deposit corrosion and plugging caused thereby, and reduce the pressure difference between the oil and gas pipeline and the annulus. The system is suitable for annulus protection of oil and gas wells, and is especially suitable for high-acid and high-sulfur oil and gas wells.

This utility model relates to the field of assisted reproductive technology, specifically to an embryo transfer tube, comprising a first tube segment and a second tube segment connected to each other. The inner diameter of the second tube segment is larger than that of the first tube segment. A piece of absorbent cotton is placed inside the second tube segment. An annular limiting seat is provided on the inner wall of the second tube segment at the end away from the first tube segment, and the inner diameter of the annular limiting seat is smaller than that of the second tube segment. By setting an annular limiting seat at the end of the larger-diameter second tube segment, this utility model can reduce the air intake cross-sectional area, increase airflow resistance, and make the negative pressure generated by the suction bulb more gradual. This facilitates the operator's precise control of the embryo aspiration position, thereby reducing the risk of embryos being accidentally aspirated into the second tube segment. Simultaneously, the absorbent cotton placed inside the second tube segment further intercepts any embryos and fluids that may be accidentally aspirated.
